The human eyes can adjust automatically the color of object under different illuminants. But digital camera does not have such mechanism, must join the white balance to simulate the color constancy of human eyes. There are many existing white balance methods. They can be categorized into two types. The first type utilizes the widespread assumption on the dealing natural scenery, which has the advantage of simplicity. Another type explores knowledge of the semantic content, which has the advantage of accuracy. In this study we modify and enhance the widespread assumption methods that can adopt the advantage of the simplicity and accuracy. Our proposed method is structured in two main parts: a color cast detector and a color cast remover. The detector first analyzes the color distribution of the image with simple statistical tools to determine whether or not the image has color cast. The remover, a modified and enhanced version of the widespread assumption methods ( gray world and max RGB ), is then applied on the color cast image. From the experiment results, it demonstrates the efficacy and performance of the proposed method.人類的視覺能夠自動修正因光線變化而改變的物體顏色，但是數位取像設備的感光元件卻不具有這樣的功能，必須加入白平衡的功能，才可模擬人眼維持色彩恆常的特性。現有的白平衡演算法可分為兩大類型，第一類型為廣泛假設型，具有運算速度快、與取像設備無關的特性，但是平均誤差會較大；另一類型為預知特性型，其特徵為準確性較高，但是運算較速度較慢、建立色彩特性資訊時所需的成本較高，本篇研究針對廣泛假設型的演算法做些修正與增強，使其具有較小的平均誤差以獲得較佳色彩品質的影像。我們將影像的色偏校正分為色偏偵測與色偏移除等兩個階段來進行，由於僅有被偵測出有色偏的影像才需要進行色偏的移除，所以可以避開將無色偏或固有色偏的影像做錯誤的修正，由實驗的結果看來，我們的方法確實有效，除了具有運算速度快、與取像設備無關的優點外，其色偏校正能力也較現有的方法好，使得影像色彩更能與人眼所見相近。

雷射光碟（以下簡稱ＣＤ）除了在電腦、音響方面有甚佳的視聽功能外，在光線照射下，呈現彩虹狀的光譜，必定引起你我研究其光學性質的興趣。國內以ＣＤ研究光的繞射的著作，有李偉等四人近三年發表五篇，國外科教期刊自1991年迄今共有19 篇，在老師指導下，利用ＣＤ進行了8 項實驗，分成三大項。1.利用氦氖雷射分別照射舊唱片、ＣＤ、ＤＶＤ，反射光形成繞射現象，由dsinθ=mλ，量出槽距。2.將ＣＤ-R 的鋁層刮掉，（整疊購買的ＣＤ-Ｒ上下有數片未鍍鋁的瑕疵片），成為透光式ＣＤ（透射式光柵），將其中心半徑5.5 公分部份，用黑紙遮住，正對陽光，螺旋狀的溝槽將陽光聚成一點，量出各色光到ＣＤ的距離，可算出色光的波長。3.透射式ＣＤ置於投影機鏡頭前方，投影機置物台上，放置化學藥品，可直接在屏上觀察吸收光譜。The rainbow of colors reflected from the surface of an audio compact disc (CD) is a familiar sight.It is the phenomenon of light diffraction. A standard CD has 20,625 turns of the spiral, and each line is spaced by 1.6μm. This provides a grating of 625 lines/mm. We used ordinary CDs as reflection grating in our experiment,and transparent factory rejects with no coating but printed data spirals as diffraction grating. We conducted eight experiments of diffraction using the two kinds of CD. (a) Determined the grating spacing of an ordinary CD using a laser beam. (b) Determined the grating spacing of a transparent CD using a laser beam. (c) Studied the diffraction patterns caused by a laser beam held at angles to a transparent CD. (d) Measured the wavelengths of sunlight using a transparent CD. (e) Measured the wavelengths of sunlight using an ordinary CD. (f) Formed a rainbow using a transparent CD. (g) Observed the scattering of light using a transparent CD. (h) Demonstrated the absorption spectrum using a transparent CD and an overhead projector.

Purpose of the research I had a bicycle accident eight months ago and I suffered an opened humeral fracture. I wasn’t able to get up on my feet, I had to suffer on the ground while a couple accidentally walked there, and they called the emergency services, I lost a lot of blood and the doctors had to cut a small piece of muscle out of my biceps. Now this shouldn’t have happened if there were a faster method on making first aid. Example an intelligent flying robot could easily handle this situation. Procedures There is a hexcopter and a quadcopter. Both of them has cameras with live image transmissions in Full HD and they also have GPS. They are equipped with a lot of sensors (image recognition with Raspberry Pi, 6 axis distance sensors, long range communication modules) and with these they are able to solve problems just a bird or a human does. These drones can communicate up to 1.8 kilometers, they communicate with the main server, they share their knowledge with each other and this way they can learn about the world and about the terrain that surrounds them. In a very basic way they are able to learn… Each time they make their flying techniques smoother and their database is growing. These drones can cooperate and save lives faster than humans do. They are also able to fly in non-accessible zones by themselves with no human help. For example with their sensors they can fly in and map buildings that are inaccessible for people. They can also do artificial farming with their object recognizing features, like recognizing plants and colors. (Right now they are calibrated to look for survivors alone in the mountains/forests.) They go to a given GPS coordinate then they are flying in a spiral form to find the injured people in less than a half hour. I really hope that one day these flying intelligent machines will save lives! Note: (I probably can only take one drone with myself to Taiwan, because of the traveling restrictions on planes.)

我們利用電腦製作了一套視力測量器，可以很快速、方便的檢測自己的視力狀況。經過大家的努力，我們自製的電腦視力測量器目前可以測量下列的項目：(1) E字視力檢測：檢查視力是否正常。測量時，電腦會自動隨機變換E字的缺口方向，讓受測者無法猜答案。測完可顯示有趣圖案和音效，告知檢查結果。我們以17 吋電腦螢幕製作，適用於受測距離2～6 公尺的空間大小。對於不同的電腦螢幕大小 (例如：12 吋～24吋)，只要改變受測距離都可適用。(2) 斜弱視檢查：利用電腦產生的亂點立體圖，戴上紅藍眼鏡，檢查是否有斜弱視。(3) 散光檢查：透過電腦產生的散光檢查表，判斷線條濃淡，可以知道是否有散光。電腦視力測量器和標準視力測量器做對照組測量比較後準確率已達 70%，所以可應用於視力檢查。而且我們使用 Power Point設計，容易透過網際網路 e-mail傳送、或在網站供大家下載使用，達到推廣視力保健的目的。

植物 VS.電磁波，如何有效降低電磁波，這是一個連我們老師都好有興趣的問題。一開始在擬訂計畫時，我們討論到很多方法，如用指南針、布、植物等… ，後來我們還是決定選擇用植物，因為植物符合方便、經濟、環保天然又安全的標準；而在中國時報上剛好也有一位國科會的教授，他曾提出了一個創意的構想：我們可以試著利用植物的大分子代替研發電器的材質等；因此我們嘗試選擇依植物的葉片形狀不同，將植物葉片分類為較厚的、大片狀的、小片狀的等；另外我們也選擇了日常生活使用率較高的機子，如映像管電視、液晶電視、手機、桌上型電腦、筆記型電腦、MP3 耳機、吹風機、微波爐等八種電器，分別以距離、時間及植物阻隔物等當操縱變因，來比較電磁波的強弱，試著找出最理想的植物阻隔物，提供給專家做為代替電器降低電磁波材質的參考。

本研究起自於玩「吉普賽人讀心術」電腦遊戲所引發的問題，配合數學「整數的簡化計算」、「因數和倍數」、「怎樣列式」單元，來探討讀心術的設計原理，並嘗試設計自己的讀心術。結果顯示：一、「吉普賽人讀心術」是以 9 的倍數來設計。二、不同的讀心術設計原理不同，但都和整數的簡化計算有關，也和倍數有關。三、設計自己的讀心術遊戲時，需考慮玩家的計算步驟不能太複雜，設計者必須有快速的步驟猜中數字。

「磁鐵」」單元要讓學生了解磁力的大小及磁場的基本概念，過去的實驗是用鐵沙吸附在磁鐵的現象及鐵沙的量來判定磁鐵的磁力及磁場的變化，但根據過去的經驗，學生還是難以轉化對磁力線及磁場的認識，於是我們除了用傳統的方式來認識磁力線外，也試著用更具新穎、更具有效率且吸引學生的方式來看看這磁力線的真面目，我們用傳統的電腦螢幕發現了磁鐵貼近螢幕時，會將他磁力線的面貌以光譜的方式呈現出來，讓我們能清楚的判定磁鐵的磁極及磁力的大小，亦能透過螢幕看見兩個磁場交互作用的微妙變化、透過水的結凍現象發現了磁力線造成水分子結構的改變，這神奇的魔力透過實驗我們找到蛛絲馬跡，感受到強大的磁場對日常生活的影響。

Whe we think of chemistry experiments in schools from the view of environmental\r protection, microscopic chemistry experiment with reduced quantity and waste is\r the trend for experiments in the future. It is also the target that everybody shall\r aim for. After many failures and instructions from teachers, I finally successfully\r performed electrolysis of the most micro-volume of one-drop solution. It was also\r unbelievable to perform quantitative test within the electrolysis time of color\r disappear from the blue cupic sulfate solution. \r To clearly see the one-drop solution electrolysis, instrument starts from magnifier\r to self-assembled micro project, then upgraded to the miro-visual screen. It not\r only can record,also plays/shows in the computer. Most importantly, it is the most\r environmental protection effective and also zero pollution microsopic chemistry\r experiment. It is obviously a target of future development trend. \r 我們從環境保護的角度去思考常校的化學實驗時，減量減廢的微型化學實驗已是未來實驗的趨勢，也是大家應共同努力的目標。在多次失敗及老師的啟發下，我終於成功的做到電解最微量的一滴溶液。對於從藍色硫酸銅溶液顏色消失的電解時間裡，還可做定量的檢定感到不可思議！ \r 為了更清楚看到一滴溶液的電解情形，儀器的設計由放大鏡到自組顯微投影機，最後進階到顯微視訊的畫面，它不但可記錄下來，而且可在電腦中播放。最重要的是：最環保也最接近零污染的顯微化學實驗，已然是未來可發展下去的目標。

蟋蟀聲音與行為的關係密不可分。取北部四種蟋蟀樣本，以數位錄音筆錄製及電腦軟體分析蟋蟀的聲音，並用PCR技術萃取蟋蟀的粒線體DNA(16S)加以分析，藉此和傳統的形態學分類相互比較。結果發現蟋蟀聲音的頻率特性中主頻率的差異在親緣遠近有關聯性，但聲音的時間特性方面則沒有特定關聯，不過聲學分析圖仍可作為單一種的鑑定指標。此外，研究發現此4種蟋蟀的聲音頻率範圍有重疊現象，但主頻率、脈衝比、唧聲率及唧聲長不同，推測雌蟋蟀應是綜合這些特性辨別同種。另一方面，以黑蟋蟀作為研究對象，進行干擾實驗，觀察並繪製出其聲音行為模式; 並將此作為對照，結果發現蟋蟀的生殖行為主要受到雄蟋蟀的聲音支配，而雄蟋蟀則以嗅覺辨別雌蟋蟀位置，決定下一步行動，與視覺較無關係。 Cricket's voice is closely related to the behavior. We select four species of crickets from the northern Taiwan to study the acoustic and mating behaviors. The digital sound recorder and acoustic software are used to analyze their acoustic characters. Furthermore, the PCR technology is used to amplify and sequence parts of mtDNA sequences and the results were compiled as the comparison to the traditional morphological character. The result shows that the resolution in acoustic characters of main frequency, pulse number, chirp rate, and the length of chirp are different among four species, though the minor frequency pattern is overlapping. Moreover, we find that frequency characteristic difference among four species is partly related to their phylogenetic relationship, yet is not seen in time characteristic. It is obvious that difference of acoustic behavior can be regarded as identified index among species. Results of acoustic analysis impel us to infer that the female crickets take the comprehensive acoustic behavior to distinguish their specific male. In addition, behavior pattern and model of Gryllus bimaculatus are established as the comparison of interfering experiment is undertaken. Which results suggest that the mating behavior in cricket is dominated by males’ acoustic behavior, and is initiated by male’s olfactory sense rather than that of sight.

The purpose of the research is to investigate the settling mode of the viscid micro-particle, such as the ones from the “Miso Soup”, in static liquid. We constructed the “constant temperature environment” by constant temperature trough and transparent glass trough. The data is gathered from pictures captured from DV and then analyzed by Media Player. We did a stability test prior to the start of the experiment and found the system with good stability. The results of the experiment are as followed: 1. The settling mode can be divided into four phases: (a) Initial accelerated phase (b) Maximum phase (c) Gradually decelerated phase (d) Stationary phase. 2. The lower the fluid concentration is in the fixed temperature: a. the faster its settling interfaces appears; and the deeper it becomes for the depth of its settling interface. b. the faster the maximum sedimentation rates of the settling interface becomes and the slower it appears. 3. At the fixed concentration, the higher temperature: a. has the bigger maximum sedimentation rates of the settling interface b. gets to the stationary phase sooner c. has shallower stationary settling interfaces d. the time when the settling interface appears is independent with the temperature 4. The shape of the container has no effect on the settling mode as the settling interface is always perpendicular to gravity field. 5. If we add salt into the liquid, the stationary settling interfaces of the result will be higher than non-added ones.本研究的目的在於探討味噌這樣的微小黏性顆粒，在靜止液體中的沈澱模式。運用恆溫槽與透明玻璃水槽所建構之恆溫環境透過數位攝影機，以電腦播放軟體於特定時間擷取畫面進行分析。在正式實驗前，進行了穩定性試驗，發現穩定性良好。實驗的結果發現：一、 沈降模式：可以分為四個時期，分別為（一）起始加速期（二）高峰期（三）逐漸穩定期（四）完全靜止期。二、 在固定溫度下，溶液濃度越低：(一) 出現沈降交界面的時間越短且穩定距離距液面越深。(二) 沈降面沈降速率最大值越大且出現的越晚。三、 在固定濃度下，溶液溫度越高：(一) 沈降面沈降速率最大值越大。(二) 沈降交界面完全靜止期出現的時間越短，也就是越快達到穩定。(三) 沈降交界面的穩定距離距液面越淺。(四) 沈降面沈降速率最大值出現的時間與溶液的溫度無關。四、 容器內部的形狀與沈降面的沈降行為並沒有影響，都是成與重力場垂直的水平線沈降。五、 添加食鹽之後最終穩定沈降面比同濃度同溫度的高了許多。表示添加了食鹽對於味噌溶液有阻止沈澱的效果。

我們先假設有一正方體及一截過正方體之平面，並設正立方體為一k*k*k 之立體。為計算平面截過之單位正立方體個數，我們必須先分別計算各層被切過之個數再將之相加，因此將各層面投影至同一平面，簡化為平面上之問題，並討論其性質／規律，計算平面截此正立方體之個數。如此，便可以一般化數學式計算平面截正立方體個數之問題。接著，用以上方法為基礎，討論各種平面切正立方體之類型，將被平面所截之單位立方體個數以電腦程式算出，觀察數字變化及其性質規則，並找出最大值發生之條件。 We initially supposed that there are a regular hexahedron consists of unitary n × n cubes and a plane which incises the regular hexahedron. To calculate the total number of the unitary cubes incised by the plane, we can first calculate them layer by layer and then sum them up. And further, we project each layer on the same plane, so the three-dimensional problem is simplified into two-dimension. By making use of the character which results from projection, we can easily calculate the number of the unitary cubes incised. Consequently, we are able to calculate them with a general equation. Afterward, we research each circumstance that the plane incises the regular hexahedron on the base of the mentioned methods. Calculate them with self-designed computer programs, and observe the regulation and change of the result. Furthermore, we can find out when it will achieve the maximum.
